Step-by-step explanation:
WHAT IS THE SET TABULAR FORM AND SER BUILDER FORM A set is mathematically denoted by capital letter that is, A, B, C…………………..Z, and any well-defined noun. we write element of the set in a small letter with bracket {…………..}. small letter maybe a b. c. d…………………..z or part of the noun. enclosed with bracket {1,23,7} called the
set builder form and mathematical use notation is called tabular form we can write set in a different form now we will explain two type form of the set (1) DESCRIPTIVE FORM (what are the proper and improper subset) ‘ read element of the set is called descriptive or roster form” set of first six natural number
set of integer zero to five in a negative direction set of the natural number between 4 and 12 The set of even integer between 2 and 5 The set of a prime number less than 12 The set of odd integer from 5 up to seven (2) TABULAR FORM write element of the set in brackets { } with commas EXAMPLE:1 N={1,2,3,4,5,6} EXAMPLE:2 Z={
o,-1,-2,-3,-4,-5} EXAMPLE3 N= {5,6,7……11} EXAMPLE:4 Z ={3, 4} EXAMPLE:5 P={2,3,5,7,11} EXAMPLE:6 O = {5 ,7} (iii) SET BUILDER NOTATION we write the mathematical notation in brackets is called set builder form. where x means set mean part of and mean less or equal to EXAMPLE:1 notation ( mean) and
Answer:
A = {3, 5, 7, 9}
B = {2, 4, 6, 8, 10}
C = {12, 14, 18, 20, 24}
D = {21, 26, 31, 36}
